To alive/ mm it may concern.

Be it known-that I, Trimmer Bic-awry, of the town of Fergus, in the county of ll ellington and Province ofOntario, Def 'minion of Canada, have invented certain new and useful Improvements in Transmis+ sion Gears; and I hereby declare that the following is a full, clear, and exact description of the same. i

' This invention relates to a transmission gear comprising a spur mounted on a driven shaft and selectively movable into and out of mesh either with pinion fixed on and rotatable with the driving shaft, or a reversing pinion fixedon and rotatable 'witlra counter shaft hav ing a driving pinion constantly in mesh with V the pinion of the driving shaft, or into neutral position between these pinions, suitable provision being made by which the spur wheel effects the revolutionof the driven shaft when in mesh either with the pinion on the driving shaft or the reversing pinion on the counter shaft, and it relates more particularly to the shift-means by which the spur wheel can be selectively brought into mesh either with the pinion on the driving shaft, or the reversing pinion on the counter shaft, or into the neutral position in which it will not be in mesh with ither of'them, this means consisting essentlally of a yoke embracmg the hub of the spur wheel and provided with an elongated arm movable axially in a-fiXed path approxi mately parallel with the driven shaft and actuated by a bell crank lever having an oscillating connection with the'arm.

F or the purpose of explaining one use of the transmission gear, the invention is shown in connection with a wringer app aratus in which:

Fig. 1 is a plan view transmission gear.

Fig. 2 is a transverse sectional elevation on the line 2-2 Fig. 1, and 7 Fig. 8 is a fragmentary cross sectional view on the line 3-3 Fig. 1.

The 'wringer roller f is provided with a shaft 5 journalled in suitable bearings 6, T and 12. The bearings 6 and 7 are mounted in standards 8 bolted or otherwise fastened to the bed plate or base of the apparatus and forming part of the main frame of the wringer, and the bearing 12 is formed in a standard 13, bolted or otherwise fastened to 'the bed plate or base. The standard 13 is Gnonen its hub to engage either of two clutch wheel loosely I one end of a connecting rod 25.

of the wringer and in parallel relation with and sufficiently spaced from'the adjacent standard 8, for the shifting movement of the spur wheel 15. T he spur wheel15 is loosely mounted on the shaft 5 between the bearings 6 and 12' and its hub 16 is formed with a circumferential groove 17. Extending transversely through the spur wheel 15 and hub 16 is a pin 18' which projects beyond the spur wheel and members 9 and 10 on the shaft '5.

j The clutch "member 9 is arranged on the shaft 5 adjacent to the bearing 6 and the clutch member 10 is arranged on the shaft adjacent to the bearing 12, the distance between the inner faces of the Clutchmemberg-being greater than the length of the clutch pin 18, so that when the spur wheel isina neutral position, or is only partlyengaged with either the driving pinion or'reversing pinion hereinafter described, the clutch pin 18 will be entirely clear of the twoclutch members. i Loosely embracing thehub 16 and entered in the groove 17 is a shift yoke 20, provided with an'arm 21 movable lengthwise through guideways 22 in the standards 8 in a plane substantially parallel to the shaft 5.

The bearing 7 is enclosed bya bracket v23 forming part of or secured to the adjacent standard 8 and fulcrumed to the bracket 23 is a bell crank lever 24:,- to which is knuckled The'other end of the connecting rod 25 is knuckled, as

' shown at 26, to, the arm 21, approximately intermediate the standardsS. The connecting rod 25 extends through a laterally elongated aperture 27 in the adjacent standard 8 for its oscillating movement as the bell crank lever 24- turns on its-fulcrum connection-28 with the'bracket 23. 'To provide a clearance between the arm 21 and the connecting rod 25, the'arm 21, as shown in Fig.

2, is bent downwardly into a plane below that of the connecting rod 25, but this arrangement may be varied within the scope of the claims without departing from the principle of the invention.

Journalled in bearings 13 in the standard 13 and in the adjacent standard 8 is a driving shaft 30 on which is fixed a grooved wheel 31. Fixed on the driving shaft 30, below the clutch member 9 is a driving pinion 32, the clutch pin 18 engages with the clutch member 9 and causes the rotation of the shaft 5 and roller 'e in a forward direction.

Journalled in bearings 13' in the standard l3 and the adjacent standard 8 is a counter shaft 33 on which is fixed a driven pinion 34L constantly in mesh with the driving pinion 32 and also mounted on the counter shaft 38 is a reversing pinion 35, spaced from the driven pinion 23 i a distance greater than the width of the spur wheel 15,, to grovide a neutral position for the spur wheel when out of mesh with beta the driving pinion and the 'ng pinion o5.

"il hen the bell crank lever A: to move the arm 21 and yoke J) limit of motion inthe direction 0 arrow shown in Figure 2, the spur wheel 15 shifted into mesh witl the drivingpinion 32 and duringits rotation the clutch pin 18 engaging with he clutch member 9, effects the revolution of the shaft 5 and roller 4;.

The meshing: of the driven pinion 34- with the driving pinion 32 causes the cont us revolution of the shaft 33 and the rev pinion 35. Ti hen the bell crank lever 2% is operated to move the arm 21 and ye: 20 to their limit of motion in the opposite direction to the arrow shown in F tie spur wheel 15 is brought into mesh witii thc reversing pinion 35 and the clutch pin 18 is engaged with the clutch member 1.0 to, cause the revolution of the shaft Sand roller e in the reverse direction,

hen the spur wheel 15, is in the neutral posit-iom-shown in F 2, the, driving shaft 30, driving, pinion 32, counter shaft. 33 and the pinions 3e and 85, can continue, their rotation without impartingmotion to the shaft 5' and roller 4;.

By so spacing the clutch members 9 and 10, that the spur wheel 15 can become part- 1y engaged with either the driving pinion 32. or reversing pinion 35- before the clutch pin will be in position to come, into cng ment with the corresponding clutch memher, the direction of rotation of the spur Wheel can be positively changed before it again picks up its load.

Partially enclosing the arm 21, and connccting rod 25, is a guard 36, which protects them from the water descending from the wringer rollers.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A transmission gear comprising a dr' *ing' shaft, a pinion on the driving shaft rei 'oluble therewith, a counter shaft, a pinion on the counter shaft in mesh with the pinion on the driving shaft, a second pinion on the counter shaft spaced from the first mentioned one, a driven shaft, a spur wheel loosely mounted on the driven shaft and selectively movable into mesh with either the pinion on the drivingshaft or the second mentioned pinion on the counter shaft or into a neutral position between them, clutch members carried by the spur wheel, and clutch members on the driven shaft engageable with the clutch members of the spur Wheel.

2. A transmission gear comprising drii: ing shaft, a pinion on the driving shaft revoluble therewith, a counter shaft, a pinion on the counter shaft, in mesh with the pinion on the driving shaft, a second pinion on the counter shaft spaced from the first mentioned one, a driven shaft, a spur wheel loosely mounted on thedriven shaft and selectively movably into mesh "1th either the pinion on the driving shaft or the second mentioned pinion on the, counter shaft or into a neutral position between them, clutch members carried by the saur wheel, and clutch members on the driven shaft ongageable with the clutch members of the spur-wheel, said last mentioned pinions be;-

so arranged with relation to the, clutch members on the driven shaft, that the, spur wheel will be fully in mesh with them for the revolution of the spur wheel before the clutch members engage.
